A horizontal load P is applied to an assembly consisting of two inclined bars, as shown in the figure.  The cross-sectional area of bar (1) is 1.30 in.2, and the cross-sectional area of bar (2) is 1.75 in.2.  The normal stress in either bar may not exceed 24 ksi.  Determine the maximum load P that may be applied to this assembly.  Assume dimensions of a=14.5 ft, b=9.0 ft, and c=14.5 ft. Make an assumption for the maximum load case, referred to as “Load Case A”, in which the force in member (1) will control the capacity of the two-bar assembly.  For this assumption, which may or may not be correct, the force in member (1) is  F1,A=F1, allow.  Enter the value of the force in member 2 for Load Case A.
